If you have some experience in bios upgrading and if nothing else helps there is a utility named CBROM.EXE this utility allows you to remove and reinsert data into the bios ..

You have the chance to test this before you burn the bios back to the chip and the most important thing is that it runs on plain DOS.here a short cutout of it:

You can do alot of things and I think with this you can also update the controller bios code in the ASUS bios - But if you never have done something like this then DON'T EVEN TRY and if you still going to then be sure to have a BACKUP CHIP READY with the original DATA of the bios of your computer .!

Use this on you OWN RISK because it may can be destructive to your Computer if used the wrong way.!!!
